Patented Sept. 26, 1905,

Application filed March 13, 1905. Serial No. 249,864.

To all whom, itnuty concern:

Be'it known that I, WILLIAM SANDERS, acitizen ofthe United States, and a resident of the city of St. Louis, Missouri, have invented certain new and useful Improvements in Churns, of which the following is a specification containing a full, clear,-and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to the class of churns known as rotary; and it consists in the novel features herein shown, described, and

' claimed.

The object of my invention is to provide an improved rotary dasher and means forv permitting the more eflicient adjustment of the dasher with relation to the spindle which carries it.

In the drawings, Figure 1 is a sectional side elevation of my improved churn. Fig.

2 is a plan view of the dasher located in the cream-receptacle. Fig. 3 is a sectional elevation of the dasher detached.

For imparting motion to the dasher I provide a vertical standard 1, which is provided at its lower end with suitable clamping-jaws 2 and 3, the lower jaw 3 having a thumbscrew 4, by means of Which the standard may be secured to a table-top, such as 5, or to any other suitable support.

Projecting from the standard 1 at a point about midway of its length is a stud-bearing 6, and mounted within said bearing is a stud 7. Fixed upon said stud 7 is a large gearwheel 8, provided with a crank-handle 9. Extending from the upper end of the said standard 1 is a horizontal arm 10, u on the inner end of which is a bearing 11 an at the outer end of which is another bearing 12. Mounted in said bearings 11 and 12 is a horizontal shaft 13, having fixed upon one end a pinion 14., which meshes with the said ear- Fixed u on the outer end 0 the shaft 13 is a beve -gear 15. Formed integral with the said bearing 12 and projectin upwardly therefrom is an inverted-U-shape frame 16. In the upper portion of the said frame 16 I provide a bearing for the upper end of the dasher-spindle 17, and another spindle-bearing 18 is formed in vertical alinement with the bearing just mentioned by extending the said frame downwardly-and inwardly, as shown in Fig. 1. A bevel-pinion 19 is fixed upon the spindle 17 at a point just above the said bearing 18.

20 Indicates the cream-receptacle, which what enlarged from about the center of its length to its upper end, and within this enlargement is firmly fixed a metallic sleeve 23 This cream-receptacle is supported carrying the thumb-screw 24 at its upper end- I The lower -end of said sleeve rests against the 3 Shoulder 25, which prevents its further upward movement.

26 indicates a smaller sleeve which telescopically engages the interior of the said sleeve 23 and is'provided at its upper end with a thumb-screw 27.

The dasher 21 is preferably in the form of a conical or tapering body with its smaller diameter at the top. Upon the outer surface of the dasher 21 are formed alternate rings 28 and annular grooves 29. Opposite walls of said grooves are preferably parallel for a distance, but terminate at their inner first be depressed as far as possible by pushing it downwardly within the sleeve 23, and this will cause the upper end of said sleeve 26 to come to rest at a short distance above the upper end of the sleeve 23. Then the dasher maybe readily adjusted to or detached from the spindle by first withdrawin the said sleeve 26 a distance from the sai sleeve 23 andv then securing the first-mentioned sleeve 26 to s indle at a short distance below the plane 0 the bevel-gear 15 and finally adjusting the sleeve 23. carrying the dasher, and securing the same by means of the thumb-screw 24.

The above-described telescopic construction of the sleeves 23 and 26 and the spindle 17 permits the dasher to be readily attached and removed while the same is located in the receptacle 20 and while the receptacle is located in proper position for operation. In other words, when the sleeve 26 is fully depressed and the dasher is resting upon the ottom of the said receptacle 20 the upper end of receptacle 20 may then be passed under the lower end of the said spindle 17. Then when the parts are adjusted to their operative position the said sleeve 26 will have a long and durable bearing upon the said spindle, and the said sleeve 23 will also have a long and durable bearing upon the said sleeve 26, making the dasher very rigid and durable. The lower end of the said spindle 17 is indicated by a short dotted line 17.

By rotating the gear-wheel 8 by means of its handle 9 motion will be imparted to dasher-spindle 17 through pinion 14, shaft 13, bevel-gear 15, and bevel-pinion 19. Owing to the relative diameters of the various gear-Wheels, the motion of the said spindle and the dasher 21 will be greatly accelerated over that of the said gear-wheel S. In other words, the peripheral speed of the dasher will be comparatively high, and the cream or milk contained in the receptacle 20 will enter the grooves 29 at the center thereof and will be drawn to the opposite walls and forcibly discharged therefrom by centrifugal force in almost continuous streams as long as the dasher is rotated. By this means the churning operation will be very quickly performed. The above-described function of the annular grooves in the dasher has been graphically represented by the curved dotted arrow 2%) in Fig. 1.

What I claim is 1. In a churn, a standard, a shaft vertically held for rotation in the upper end of said standard, a pinion fixed upon said shaft, a train of gearing carried by the standard and arranged to drive said pinion, a sleeve adjustably held upon the lower end of the shaft, a cylindrical dasher provided in its upper end with a vertical bore, a sleeve positioned in said bore and adapted to receive the firstmentioned sleeve, and a set-screw passing through the upper end of the second-mentioned sleeve for engagement with. the firstmentioned sleeve, substantially as specified.

2. In an improved churn, a cylindrical dasher having formed in its surface a series of horizontally-arranged, uniformly-sized annular grooves; flat-faced ribs of uniform size separating said grooves, there being a vertical bore formed in the upper end of said dasher; asleeve positioned therein; a second sleeve adjustably positioned in the first-mentioned sleeve; a shaft on which the secondmentioned sleeve is adjustably positioned; a frame in which the shaft is vertically held for rotation; a pinion fixed upon said shaft, and a train of gearing carried by the frame for imparting rotary movement to said pinion and shaft, substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.
